Probably dosen't have one. Most GM just use air doors to control temp. What is the problem?

Hello Jerry.

The base timing is preset when the engine is made, the position sensors are not movable, so no adjustment is possible. Timing advance and ****** are adjusted through the power train control module (PCM) with ignition control module.
Because the timing changes all the time from various inputs it wouldn't be an accurate reading.

No heat

are you getting any air into cabin?? cause if you ar getting air but its not coming out hot then it may be a bad heater control valve. If you are not getting any air period then its a bad blower motor or blower motor relay.

I have a 1994 Pontiac Firebird Trans Am with an automatic transmission. I get an intermittent service light and a P0029 code is referenced. When this happens the car seems shift harshly. I thought P0029 is...

It's an exhaust valve inside the transmission, when the solenoid isn't working right, the pressurized fluid can't exhaust through the passages, which can cause rough shifting. It has to be taken to a transmission shop, the transmission pan has to be dropped and possibly the valve body to get at the solenoid. Hope this helped.

I have a 2002 pontiac firebird v-6 3800. The heater hoses run into a part that is attached to the motor. I am trying to find the name of the part so I can replace it or find an engine diagram for that...

Paul, if you mean "radiator hose" then the part is the thermostat housing.

Perhaps the part is the bypass valve, which causes the heated water to "bypass" the heater core if the core is restricted.

1994 pontiac firebird HAS NO HEAT

Okay. warm up vehicle, get radiator hoses hot.  Turn on heater, fan on low.  Grip both rubber heater hoses close to the firewall, from the engine compartment side.  They should be too hot to hold for long.  If they are not hot, then you have a lack of coolant circulation to the heater hoses.  If they are hot then access heater core, behind glove box area.  Blend door which moves as you chose HOT or Cold, should be cable controlled, move the controls and be sure the door is actually moving. Keep me posted
